In chemistry, as in other sciences, calculations involving radicals are often used to explain observations and predict results. In Discover, you found that you could add radicals if the radicals were like terms. The same is true of subtracting radicals.

Example
are like terms, since each has a radicand of 6 and an index of 2 (since the square root is taken for both).
